ABSTRACT Novel H3N2 influenza viruses (H3N2v) containing seven genome segments from swine lineage triple-reassortant H3N2 viruses and a 2009 pandemic H1N1 (H1N1pdm09) matrix protein segment (pM) were isolated from 12 humans in the United States between August and December 2011. To understand the evolution of these novel H3N2 viruses in swine and humans, we undertook a phylogenetic analysis of 674 M sequences and 388 HA and NA sequences from influenza viruses isolated from North American swine… 
Pathogenicity and Transmissibility of Novel Reassortant H3N2 Influenza Viruses with 2009 Pandemic H1N1 Genes in Pigs
Three H3N2 reassortant viruses that contain 3 or 5 genes from A(H1N1)pdm09 isolated from diseased pigs were pathogenic in pigs, similar to the endemic H3n2 swine virus, and an avian-like glycine at position 228 at the hemagglutinin (HA) receptor binding site is responsible for inefficient transmission.
A North American H7N3 Influenza Virus Supports Reassortment with 2009 Pandemic H1N1 and Induces Disease in Mice without Prior Adaptation
Several genome segments of the 2009 H1N1 virus are also highly compatible with a low-pathogenicity avian H7N3 virus and that these reassortant viruses are stable and not attenuated in an animal model.
Continual Reintroduction of Human Pandemic H1N1 Influenza A Viruses into Swine in the United States, 2009 to 2014
It is shown that the six internal gene segments from pH1N1 viruses are likely to be sustained long term in the U.S. swine population, with periodic reemergence of pandemic hemagglutinin (HA) and neuraminidase (NA) segments in association with seasonal pH 1N1 epidemics in humans.
Antigenic Distance between North American Swine and Human Seasonal H3N2 Influenza A Viruses as an Indication of Zoonotic Risk to Humans
Antigenic assessment of swine H3N2 provides critical information for pandemic preparedness and candidate vaccine development and identified swine strains to which humans are likely to lack population immunity or are not protected against by a current human seasonal vaccine or CVV to use in prioritizing future human CVV strain selection.
Isolation of influenza A(H3N2)v virus from pigs and characterization of its biological properties in pigs and mice
It is demonstrated that A(H3N2)v causes a high morbidity rate with low virulence; however, global monitoring of A( H3N 2)v outbreaks in mammals will be needed to determine whether this novel subtype will shift to a highly pathogenic virus.

The increase in genetic diversity of the virus in the US swine population and the inclusion of human influenza genes in swine viruses has important implications for human health, including the enhanced potential for virus adaptation and cross-species transmissibility.
Molecular evidence for interspecies transmission of H3N2pM/H3N2v influenza A viruses at an Ohio agricultural fair, July 2012
Prospective influenza A virus surveillance among pigs at Ohio fairs resulted in the detection of H3N2pM (H3N 2 influenza A viruses containing the matrix (M) gene from the influenza A (H1N1) pdm09 virus), which were temporally and spatially linked to several human H3n2v cases.
Genotype patterns of contemporary reassorted H3N2 virus in US swine.
A phylogenetic analysis at a whole genome scale of North American swine influenza viruses suggests that the genetic requirements for transmission to humans may be restricted to a specific subset of swine viruses.


Pathogenicity and Transmission in Pigs of the Novel A(H3N2)v Influenza Virus Isolated from Humans and Characterization of Swine H3N2 Viruses Isolated in 2010-2011
In vivo study detected no increased virulence in A(H3N2)v or rH3 n2p viruses compared to endemic H3N 2-TRIG virus, and continued monitoring of these H3n2 viruses is necessary to evaluate the evolution and potential loss of population immunity in swine and humans.
Multiple reassortment between pandemic (H1N1) 2009 and endemic influenza viruses in pigs, United States.
Novel reassortant viruses detected in commercial pig farms in the United States highlight the increasing complexity of influenza viruses within pig populations and the frequency at which viral diversification occurs in this ecologically important viral reservoir.
The M Segment of the 2009 New Pandemic H1N1 Influenza Virus Is Critical for Its High Transmission Efficiency in the Guinea Pig Model
The data showed that the M segment of the Cal/09 virus promoted aerosol transmissibility to recombinant viruses with PR8 and sw/Tx/98 virus backgrounds, suggesting that theM segment is a critical factor supporting the transmission of the 2009 pandemic virus.
Swine-origin influenza A (H3N2) virus infection in two children--Indiana and Pennsylvania, July-August 2011.
Clinicians who suspect influenza virus infection in humans with recent exposure to swine should obtain a nasopharyngeal swab from the patient for timely diagnosis at a state public health laboratory and consider empirical neuraminidase inhibitor antiviral treatment to quickly limit potential human transmission.
Whole-Genome Analysis of Human Influenza A Virus Reveals Multiple Persistent Lineages and Reassortment among Recent H3N2 Viruses
A phylogenetic analysis of 156 complete genomes of human H3N2 influenza A viruses collected between 1999 and 2004 from New York State, United States demonstrated that multiple lineages can co-circulate, persist, and reassort in epidemiologically significant ways, and underscore the importance of genomic analyses for future influenza surveillance.
Emergence of novel reassortant H3N2 swine influenza viruses with the 2009 pandemic H1N1 genes in the United States
The emergence of novel reassortant H3N2 SIVs demonstrates reassortment between pH1N1 and endemic Sivs in pigs and justifies continuous surveillance.

Outbreak of swine influenza in Argentina reveals a non-contemporary human H3N2 virus highly transmissible among pigs.
This is the first report of a wholly human H3N2 IAV associated with clinical disease in pigs in South America and highlights the importance of two-way transmission of IAVs and SIVs between pigs and humans, and calls for enhanced influenza surveillance in the pig population worldwide.
Reassortment of Pandemic H1N1/2009 Influenza A Virus in Swine
Through systematic surveillance of influenza viruses in swine from a Hong Kong abattoir, a reassortant progeny of H1N1/2009 with swine viruses is characterized, which could produce variants with transmissibility and altered virulence for humans.
